Preheat oven to 400°Place all ingredients (chickpeas, onion, garlic, tahini, spices and bread crumbs) in a food processor and pulse until blended but mixture still maintains some texture.
Shape mixture into 3-inch by 1/2 inch patties. In a cast iron skillet, heat oil over medium high heat and then pan fry for 2-3 minutes, until they begin to brown. Transfer to the oven and bake for 20 minutes, flipping halfway through cooking time.
